Simplify the following:
x^3 x^2
x^3 x^2 = x^(3 + 2):
x^(3 + 2)
3 + 2 = 5:
Answer: x^5
You know if it's not reducible when there isn't any way to factor it using the grouping method. However, you should try to use the quadratic formula to find the roots after attempting to factor. If it still doesn't have any roots, that means the quadratic's vertex is either above or below the x-axis and is facing the other way. (meaning that it never touches the X-Axis)<span />

The correct answer is B.
In order to prove which of the function rules provided is the one corresponding to the schedule represented by the table, the different y-values need to be sustituted in the function rules. <u>Only the correct function rule will yield the corresponding x-value. </u>
<u>Let's prove that option B is the correct one</u>
FUNCTION B y= 5x - 14
- If x= -4 --> substituting: 5(-4) - 14= -20 - 14= -34 therefore, y= -34 <u>CORRECT</u>
- If x= -1 --> 5(-1)-14 = -5 - 14= -19 therefore y= -19 <u>CORRECT</u>
- If x= 2 --> 5(2) - 14= 10-14= -4, therefore y= -4 C<u>ORRECT</u>
- If x= 4 --> 5(4)-14= 20-14= 6, therefore y=6<u> CORRECT</u>
- If x= 7 --> 5(7) -14= 35-14= 21, therefore y=21 <u>CORRECT</u>
Answer:
neon: 0 percent change oxide: -2 percent change copper: 2 percent change tin: 0 percent change
Step-by-step explanation:
Neon: -10+10=0
Oxide: -10+8=-2
Copper: -27+29=2
Tin: -50+50=0
